Good point. From 1968-1970 the Stooges, Faces, Rolling Stones, Jeff Beck, Led Zeppelin, Velvet Underground, Neil Young, The Who, The Band, Bob Dylan, and all the rest were just churning out paint-by-numbers, psychedelic, hippy dippy anthems to peace and love.
You know, songs like: "Communication Breakdown", "What Goes On", "Pinball Wizard", "I Wanna Be Your Dog". "The Night They Drove Old Dixie Down", "The Wicked Messenger."
Black Sabbath and Deep Purple were from 69. And you can't say either of these bands was hippie music.
